But the Academy is where I can
try out all sorts of things
لكن الأكاديمية هي حيث أستطيع تجربة 
شتى الأشياء والتفكير في ذلك، صحيح؟
Auf der Akademie hat man Zeit
zum Nachdenken und ausprobieren.
La academia está para probar cosas.
La academia está para probar cosas.
Anche riflettere e fare mille cose 
fa parte dell'Accademia, no?
Mas a Academia é onde posso tentar
várias coisas e pensar nisso, não é?
Но в Академии
 можно попробовать всякое-разное!
